Chris and Joetta Harris’ middle child, Aaron, was diagnosed with cortical dysplasia, epilepsy and autism. Joetta Harris said that after a year considering the option and doing research, her and her husband decided that a service dog was in Aaron’s best interest. Aaron was prone to wander, a symptom of his autism that has caused his parents plenty of worry.”For us it’s peace of mind,” said Joetta Harris. Among Cy’s most important skills is his ability to track Aaron, but his job doesn’t end there.
